Smart Trolley Grid

The electrical bus for the future

Smart Trolley Grid, allowing us to have 100% zero-emission bus trips.

Trolley Bus 2.0

Meet the new trolley buses

The current trolley buses are equipped with a diesel generator which is not zero emission. The new trolley 2.0 buses come with a second-use EV battery pack, which means that the buses are zero emission, moreover, just like electric cars, the buses can cover a large travel distance without needing to be connected to the trolley line (charging).

The new buses are reliable, flexible and future proof!

How it works

The magic behind the new electric buses

The new trolleys have a second-use EV battery pack on board. Buses drive and feel the same, however, every time the bus breaks, the battery packs charge. This is thanks to braking energy recuperation technology is also known as IMC (In Motion Charging).

This ensures that the energy provided by the power grid is utilized to its maximum potential.

Another great benefit is that our trolley buses will be able to drive autonomously with their second-use EV battery pack for a wide kilometer range. Meaning that different regions that were hard to reach through limitations of the trolley grid will now be accessible.

Why choose the Smart Trolley Grid?

Working towards a 100% Zero emission future

  • Friendly for environmental zones

    There are more environmental zones in more cities than ever before. Using non-emission free vehicles is not allowed in those zones.

  • Clean and free from emissions

    The current trolley is already clean, free of emissions. Only in case of powerdip and in emergencies when the trolley must detour, the auxiliary power unit can be used. This is driven by a fuel engine, is not zero-emission.

  • High-tech second-use EV batteries

    For the future, the trolley 2.0 has traded in the generator (inc. fuel tank, and other accessories) for high tech second-use EV batteries.

  • Motion charging

    Second-use EV batteries inside the bus get charged while being in motion. No extra charging time required.

  • Uninterrupted driving

    The advantage is the buses can now drive without interruption, for at least 10kms, after the overhead wire stops.

  • Bigger coverage area

    Trolley 2.0 buses will be able to reach more stops and towns that are currently reached by non-trolley busses. No fuel needed, does not need to charge while standing still.

  • Self-charging second-use EV battery

    Reliable and powerful self-charging second-use EV batteries will be placed on all new trolleys.

  • More stops, more towns

    The new trolley buses will come equipped with a self-charging second-use EV battery. Allowing complex intersections, shunts, and exchanges to be eliminated, which always limited the range of our trolleys.

  • Less grid maintanance

    Most hours spent maintaining our current trolley grid are used to manage intersections, shunts and exchange parts of the grid. With the new trolley buses, this will be a thing of the past.

  • DC powered

    Solar panels and wind turbines are connected to the grid through DC power. Providing a constant stream of green energy to operate from.

The Innovation

Charge your electric car with left-over trolley electricity. Not only will our new busses drive on a 100% zero emission basis, they will also share their (excess) electricity with people that connect to the poles. Each smart pole will have second-hand car second-use EV batteries on the inside, a solar panel and a power outlet to connect to.

Companies involved in the project will be shown on a sticker on each pole.

A smart controller will be placed on each pole to monitor its second-use EV battery health and availability.

The poles can be added to our landscape without needing to dig large holes. No downtime when installing the new poles.

Every pole will come with its own cluster of second-use EV batteries, here’s where the power will be stored and shared from.

What is the Smart Trolley Grid (STG)?

Introducing the infrastructure

Smart trolley grid is a collaboration of technical specialists, government, and public transportation companies. With the goal to improve the infrastructure of electrical transportation in our city.

  • Total trolley length of 60km
  • 43 articulated trolley buses
  • 6 lines

Smart trolley grid is a collaboration of technical specialists, government, and public transportation companies. With the goal to improve the infrastructure of electrical transportation in our city.

  • Serving an area populated by 180,000 inhabitants
  • Including 137 trolley bus stops
  • Serving 27,6 million passenger kilometers in 2016

Goals

Charge electrical vehicles and store excess energy from the trolley grid in Arnhem by transferring the stored (breaking) energy into second life e-car batteries.

Eliminate complex intersections to help with the further expansion of the grid.

Combine different green energy like solar panels and wind turbines through DC power to the smart trolley grid.
